Description

Pilot signal state prompting method, base station controller and mobile switching center

The present invention relates to the field of mobile communication devices, and in particular, to a pilot signal state prompting method, a base station controller, and a mobile switching center. Background technique

In a CDMA (Code Division Multiple Access) network, when two mobile terminal users A and B establish a call, their network topology simplified model is shown in Figure 1, including the base station corresponding to the A user. The system BS1, the mobile switching center MSC1, the base station system BS1 corresponding to the B user, and the mobile switching center MSC2. The BS is a wireless transceiver device of a CDMA network, and mainly performs wireless communication with a mobile terminal. The MS is responsible for mobile user traffic management.

When the terminal user talks, the terminal reports the currently detected pilot strength to the BS. When the terminal user is in a wireless environment with strong signals, the reported pilot strength value is larger, and vice versa. Therefore, the BS can monitor the terminal pilot strength in real time, and determine the strength of the wireless environment signal in which the terminal user is located according to the magnitude of the pilot strength value.

When the environmental signal of the terminal user A is worse, the value of the pilot strength detected by the BS1 is smaller. When the value is small to a certain extent, the A user may have an abnormality such as a call disconnection and a call without sound, due to A. If the user is abnormal, the B user will also have a call abnormality. For example, a lot of words are spoken to the A user, but the A user's response is not heard, which seriously affects the communication quality and reduces the user experience.

Finally, the mobile switching center corresponding to the peer terminal sends a prompt message to the peer terminal, where the prompt information may be voice prompt information, that is, the mobile switching center corresponding to the peer terminal sends voice information to the peer terminal, and the main content of the voice information It is the difference of the pilot signal status of the first terminal, for example, "Friendly reminder: the user signal of the current call is poor, and the call may be abnormal." Or sending the text information to the peer terminal, for example, the short message, and the main content of the short message is the pilot signal state difference of the first terminal. Considering the actual application scenario, the user who is in a call cannot usually check the received short message in time. Therefore, the method of sending the short message may cause the peer terminal user to know the pilot signal of the first terminal after ending the call. The state is poor, and its timeliness is poor compared to the way of voice prompting. Similarly, you can also use the method of sending voice prompts and text messages at the same time. In addition to short messages, text messages can also include multimedia messages or emails.

In the pilot signal state prompting method disclosed in this embodiment, the base station controller receives the pilot strength reported by the first terminal and performs detection, and when the pilot strength is less than the preset threshold, sends a prompt to the mobile switching center corresponding to the peer end.
